Abstract

The utility model relates to an automatic lifting gantry elevator belonging to the vertical transport machinery for construction. The utility model is designed to overcome the defects of difficult assembly and disassembly and excessive steel consumption of the gantry elevator. The utility model is composed of a top beam, two guide bracket, a bottom frame, a drag rope, a cage, an inclined strut, a weight box, a hoister, a staple bolt and an automatic lifting vertical frame, wherein, the automatic lifting vertical frame is mainly composed of a vertical frame derrick mast, cage pulley wheels, derrick mast pulley wheels, top beam lifting pulley wheels, a hand-operated winch, a vertical frame support, a tackle, etc. The utility model has the advantages of simple assembly and disassembly and little steel consumption, and the height can be flexibly provided with the different heights of buildings.

Description

Arch type lifter with automatic lifting function

The utility model belongs to the vertical transport facility that a kind of building operation is used.

Over the years, adopt traditional well cabinet frame vertical transport material in the building operation, this facility consumption steel are many, dismounting loss steel are many, mounting or dismounting are artificial many, particularly lack safety gear, and accident happens occasionally; And adopt than advanced tower crane and SC type building hoist; cost an arm and a leg; single-rail elevator and gate-type gig have appearred at present; though possess light advantage, the former need draw cable rope at a distance, and lacks the necessary security device; latter's safety gear is unsound; individual design electromagnetic type breaking rope protecting hook, but electric wire needs with cage to lack safe, easy, the perpendicular rack device of fast speed during mounting or dismounting at high dry running.

The purpose of this utility model is to provide a kind of jack up arch type lifter safe, easy, the perpendicular rack device of fast speed that has, and its hoisting depth can be provided with flexibly, to adapt to the construction needs of differing heights building.

The purpose of this utility model is achieved in that

A kind of jack up arch type lifter, comprise back timber, two pier guide rail brackets, underframe, drag-line, cage, diagonal brace, weight box, winch and anchor ear, the top of guide rail bracket and back timber, the bottom connects to form closed portal frame with underframe, weight box is positioned at the portal frame two bottom sides, the utility model has designed the perpendicular rack device of a jack up in system, this device is by perpendicular frame gin pole, the gin pole pulley, the back timber lifting pulley, back timber, coaster, standard knot to be installed, perpendicular frame supports, the cage pulley, hook, the hand winch, the bottom standard knot, cage and winch are formed, the back timber central through hole is passed at perpendicular frame gin pole top, the bottom is sleeved on the steel pipe on cage pulley top, the gin pole pulley is equipped with in perpendicular frame gin pole upper end, steel rope twines with the back timber lifting pulley by behind the gin pole pulley, one end of steel rope is wound on the hand winch that is installed on the cage, dress perpendicular frame in cage top supports, perpendicular frame supports the top through hole and entangles perpendicular frame gin pole, the steel rope of winch is worn the pulley on back timber and cage, per two pulley rooms are hung a coaster on the back timber, and hook is installed on the cage.

The utility model is owing to the perpendicular rack device of employing jack up, thereby the mounting or dismounting dress conveniently, and consumption is manually few, and it is few that mounting or dismounting consume steel, is convenient to simultaneously transport and keeping.And since two pier guide rail brackets be by standard knot by the joint be formed by connecting, thereby its height can be provided with flexibly with the difference of depth of building, improved the practice of construction needs of elevator to the differing heights building.

Below in conjunction with accompanying drawing the utility model is further described

The jack up arch type lifter, comprise back timber 1, two pier guide rail brackets 2, underframe 5, drag-line 3, cage 7, diagonal brace 10, weight box 4, winch 6 and anchor ear 8 and stop layer shelf 9, the top of guide rail bracket 2 and back timber 1, the bottom connects to form closed portal frame with underframe 5, weight box 4 is positioned at the portal frame two bottom sides, be provided with the perpendicular rack device of jack up in the system, this device is by perpendicular frame gin pole 13, gin pole pulley 11, back timber lifting pulley 12, back timber 1, coaster 14, standard knot 15 to be installed, perpendicular frame supports 16, cage pulley 17, hook 18, hand winch 19, bottom standard knot 20, cage 7 and winch 6 are formed, back timber 1 central through hole is passed at perpendicular frame gin pole 13 tops, the bottom is sleeved on the steel pipe on cage pulley 17 tops, gin pole pulley 11 is equipped with in perpendicular frame gin pole 13 upper ends, steel rope twines by gin pole pulley 11 backs and back timber lifting pulley 12, one end of steel rope is wound on the hand winch 19 that is positioned on the cage 7, dress perpendicular frame in cage 7 tops supports 16, perpendicular frame supports 16 top through holes and entangles perpendicular frame gin pole 13, the steel rope of winch 6 is worn around back timber 1 and the pulley that hangs on 7, per two pulley rooms are hung a coaster 14 on the back timber 1, and hook 18 is installed on the cage 7.

Its principle of work is as follows:

At first on the basis, set level underframe 5, load onto bottom standard knot 20 and weight box 4, diagonal brace 10, put cage 7, back timber 1 is rested standard knot 20 tops, bottom, load onto winch 6, install perpendicular frame and support 16, perpendicular frame gin pole 13, hand winch 19, hang up coaster 14, wind the back timber lifting wire rope by Fig. 4, upright two save standard knots 15 to be installed and tie up the jail in cage 7, start winch 6, when rising to, cage 7 stops when requiring the position, unclamp the hook connecting rod, hook 18 is hung on the cross bar of standard knot 20, after hanging up properly, hand winch 19 is rotated in winch 6 counter-rotatings simultaneously, and back timber 1 is promoted to the extreme higher position, the coaster 14 of leaving behind then, standard knot 15 to be installed on the hook, winch are just changeing lifting standard knot 15 to requiring to rotate about 20 ° again behind the position, and standard knot 15 to be installed is alignd with bottom standard knot 20, then standard knot 15 to be installed is placed on the standard knot 20 of bottom, the two connects the jail to make it with bolt, and the hand winch 19 that reverses again rests back timber 1 on the standard knot 15 that newly installs, so far two joints just install, and all the other each joints get final product by above-mentioned the installation with quadrat method.
